Something doesn't seem to add up with that, as Comcast has 20M and Dish has 10M. It doesn't make sense that landing those two would put it ahead of the SECN because isn't the SECN on everywhere?

That said, the SECN's 59M might not have included Altice, which they actually weren't on (one of the few) until the last deal.

But if you assume the premise "SECN has universal carriage" then these numbers are sketchy somewhere.

I've read that the deals that the conference networks have made with carriers provide that at least 80% of the customer base must receive the conference network. That allows the carriers to sell a low cost, very basic package to its most cost conscious customers. That means that Spectrum signing a deal with the ACC doesn't mean that all of Spectrum's customers will get the ACC network. That would also be why SECN's total seem to be less than what you get by adding all the customers of all the carriers they've signed contracts with. Of course, that 80% number may or may not be what is specified for ACCN. That percentage may have been one of the items bargained over.
